The Dry Tortugas are the western extension of an arcuate chain of Pleistocene reef and oolitic limestone islands, with the eastern limit in the vicinity of Miami. These Florida Keys are the surface expression of the 3.7 mi (6.0 km) thick southern Florida carbonate platform, which has been accumulating sediments since the Early Cretaceous.
